Why have scientists so far found no oceans or lakes on the surface of Mars? Two new studies suggest that a Martian dust storm can form an 80-kilometer-high dust tower-like structure, a powerful storm strong enough to “suck out” the reservoir on the surface of Mars. The two studies are based on 2018 Martian weather data, when a dust storm swept across the planet, causing NASA’s Opportunity probe to end its mission unexpectedly.
During the storm, the researchers observed a huge dust tower structure, as wide as Rhode Island, and at an altitude of 80 kilometers, sending gas vapor and dust particles into the Martian atmosphere. The researchers point out that these towers release water vapor from the surface of Mars to the upper atmosphere of Mars, where strong solar radiation can cause water vapor to separate from dust particles.
Scientists say mars has this huge dust tower structure every decade or so, said Nicholas Heavens, a scientist at the University of hamptons. The dust tower structure will last for several weeks. “
Dust towers are like “space elevators”, and observers can see how much of the surface matter it transports to the Martian atmosphere, after Hanvins’ research showed that Martian dust storms can carry water vapor and dust particles into the Martian upper atmosphere, which could explain periodic small white clouds on the surface of Mars.
As storms periodically gather, the phenomenon will sweep across the planet, rather than exist independently, or explain the mystery of the disappearance of water on the surface of Mars, said David Kass of NASA’s Jet Propulsion Laboratory. The phenomenon can affect the Martian climate for several months. “
